Emerson EZ1000 Eddy Current Measurement System

Overview

The AMS EZ 1000 is a modular eddy current measurement system for machinery health monitoring. It combines a sensor, cable, and converter, available individually or as a complete chain. Furthermore, it reduces downtime, simplifies inventory management, and meets API 670 standards. The system monitors vibration and displacement in rotating machinery with high precision.
